I was there last year a day or two after. Getting accomommodation was a problem as was hiring scooters. I'm going this year but I've delayed until after the festival. It's crowded enough at the best of times.

Yes it will be busy but the bustle and vibrancy of the occasion is all part of the experience. If you want to hire a bike any time in October its best to reserve one before you go but there are still plenty of other options for getting around and away from the crowds if you want to. I was there throughout the festival period last year and even entered the open 2 day competition, all great fun, and for the 20 euro entry fee we got a goody bag with around 60 euro's worth of tee shirts, hats, chalk bags etc, plus a free meal and several free beers. If you want total peace and mountain solitude Kalymnos won't be for you at this time of year.

I was there for 2 weeks over the festival last year and the routs were were after were fine, little crowding. Eating out was a bit crowded at times, all told I enjoyed it. I've been there 3 times in 3 years and being there for the festival wasn't a great disadvantage

We were there last year and frankly it was hellish. The place was weighed out so unless you want to be part of the festival (and I can't imagine why you would) I'd say steer clear. When we booked we had no idea there even was a festival. Most places use events like festivals to encourage people to come and fill accommodation during slack periods. Why the hell Kalymnos has one at a time when it would be busy anyway is quite beyond me.
Never again!

In reply to Wiley Coyote: I guess it depends on what you like - I was there last year for the festival, and with the exception of Odyssey, it wasn't too busy - we rather enjoyed the atmosphere. You couldn't hire a scooter for a few days, as they had all been pre-booked, but that was the only negative.

In reply to sammiKrogers: God, avoid it when that's on. Too many people, and it's verging on chaos at times! Unless you're taking part or are desperate to see sport climbing stars then it will be a waste of time for you.
